Blue screen appears when windows starts. Blue screen on a laptop what to do. Viruses and security software

o Viruses, the cause of the blue screen is quite rare.

Of course, to solve the problem of the blue screen on our computer, it is very good to find out first the reason for its appearance. To do this, the operating system displays us the relevant information on a blue screen, which is basically the same, except for two small items - the name of the error and the error code.
How to decipher the blue screen error. Let's take a look at two cases that you may have.

· A blue screen appears when the computer boots up and remains on the screen for a long time, giving us the opportunity to read the name and error code.

· The blue screen appears when the computer boots for a second and disappears, while the computer goes into reboot again, so we don't have time to read anything (about this complex option below).

You cannot rely on solving the blue screen problem, only on decoding error codes. One and the same error, for example 0x0000008E, can indicate a malfunction of the RAM and at the same time a rootkit infection, and another error 0x0000000A IRQL_NOT_LESS_OR_EQUAL, can indicate dozens of reasons. But reinstalling Windows right away, if a blue screen occurs, is also not worth it, you still need to try to figure out what's the matter ...

So that in the event of a critical error your computer does not constantly restart and you can read the error code on the blue screen, the first thing to try is when you turn on the computer, press the F-8 key on the keyboard and go to the Advanced boot options menu, then select the item Disable automatic restart on system failure,

If it does not help, then it will not be superfluous for you to know such information. I want to say that the operating system is able to save information about the blue screen error in a special file called a memory dump, it will be located in the C: \\ Windows \\ Minidump folder. But for this you need to enable recording of Windows debug information. Do it now.

On Windows XP:
Right-click on My Computer, then Properties-\u003e Advanced-\u003e Startup and Recovery Options-\u003e System Failure-\u003e Disable the Auto-restart option. Select Small memory dump (64 KB) and click OK.

.

We select the memory dump with the left mouse in the upper window of our program and immediately look at the lower window, there will certainly appear information about the error. By the way, if you press F-8 while the program is running, then our blue screen will appear in the lower window.

Microsoft has its own debugging tool, but I would say the BlueScreenView utility is simpler, and the result is no worse.
You may ask, our computer does not boot, how can I reinstall the audio driver? First, you need to try to roll back a certain period of time using system restore points, this can be done in safe mode or in the Windows 7 troubleshooting menu (when booting the F-8) or from the recovery disk of the seven. To remove the problematic driver, in case of a blue screen, you can try to enter safe mode with command line support and type the command devmgmt.msc and you will be taken to the device manager.

After removing the problematic driver, you need to install updated driver versions, preferably taken from the official websites of device manufacturers. Or vice versa, install an old and stable driver.

Now let's move on to a more difficult question. What to do if a blue screen appears for a second and it is not possible to read the title and error code?

Booted from a simple Live CD and there is the same thing, there is no disk (C :).
I boot into the Acronis Disk Director 11 program, my disk (C :) is visible and the data on it is all intact, but nothing can be done with them, for any operation with the partition, Acronis immediately gives an error The file system is damaged!

The utility for checking the hard disk CHKDSK, which exists in Windows 8 or 7, immediately detected the problem disk with a damaged file system and began checking it for errors in five stages: checking files, checking indexes, checking security descriptors, checking data in files and checking free space!
I had to wait three hours, then reboot and my system boots up safely, and the missing partition of the connected hard drive also became available. In general, friends are the first sign that the hard drive will soon become unusable and needs to be checked with special programs, for bad sectors and Bad blocks (bad or bad sectors). If everything is more or less successful, in order to use such a hard drive, ideally format it completely and reinstall the operating system on it.

Friends, when your operating system does not boot due to errors on the hard disk, then you do not need to remove it to check the Chkdsk utility, you can boot the computer from the Windows 7 installation disk or the recovery disk, then enter the recovery environment, select the command line, then enter the command:
chkdsk c: / f, which means run system disk check (C :) with / f parameters - checks for file system errors on the disk and fixes them. Details in our article: Chkdsk program.

Another example: an old friend of mine, spent a long time looking for the cause of a blue screen on one computer. A newly installed operating system, with native drivers installed on all devices, after 5-10 minutes of running any active application (for example, a game), went into a blue screen with a Stop: 0x00000019 error. Practically all components were tested, including the Mem test program, 512 MB of RAM was successfully tested, which in the end turned out to be to blame. The fact is that a computer with a relatively weak configuration had a powerful gig video card, and only 512 MB of RAM. He replaced the 512 MB RAM bar with 1 GB and the blue screen stopped appearing, the old RAM bar still works on another computer with an integrated video card.

· My friends bought a computer, two years have passed and from time to time, when playing games, a blue screen began to appear. We decided to reinstall the system. We reinstalled and began to install drivers on all devices; when installing a driver on a video card, the system went into a blue screen. Updating the driver on the official website did not work, the problem was solved only by replacing the video card. By the way, on another computer, this video card behaved the same way.
· Exactly the same was the case with a network card installed in the form of an expansion card in a PCI slot. We went through all possible and impossible drivers, when installing the driver, Windows 8 showed a blue screen with an error and went straight to reboot, not allowing the name and error code to be read. The network card was replaced and everything worked fine.

Sometimes people are looking for the cause of the blue screen for a long time, reinstalling the system, drivers, and the matter is in the banal overheating of the processor, it is worth removing the side wall of the system unit, looking at the dust cap on the processor cooler and everything will become clear.

· Overclocking the processor, also often the cause of the blue screen, is treated by resetting the BIOS settings.

· Once friends, I was very much asked to save the Windows 8 system from the blue screen, they were not limited in time, they gave me a whole day. The error code could not be found, the operating system was rebooting all the time. First of all, just in case, I made a backup of the faulty system, namely the system partition -disk (C :). If you can't fix the problem, I'll deploy the backup and give the computer back unchanged, maybe someone else will succeed.

I tried almost everything that can be done in this case, last of all I tried this method - I replaced all SAM, SEKURITY, SOFTWARE, DEFAULT, SYSTEM registry files from the C: \\ Windows \\ System32 \\ config folder with the same files from the C folder : \\ Windows \\ System32 \\ config \\ RegBack, in it every 10 days the Task Scheduler creates a backup copy of the registry keys - even if you have System Restore disabled and Windows 8 has booted safely.

The death screen is caused in Windows 7 by system errors classified as critical. The OS hangs and the last user changes are not saved.

The situation is not the most pleasant, but it is often encountered in computers with the "Seventh" system modification.

There is no general algorithm of actions to fix this problem, as it depends on the causes that caused it. Below are specific recommendations that should be taken to effectively resolve the situation that has arisen.

Why does the screen of death appear?

All the abundance of reasons that cause BSoD are classified into two large parts:

1. Software;
2. Hardware.

The first includes failures in system services, incorrectly installed software (including those that ensure the normal functioning of equipment - drivers), virus infections of a PC, software conflict, etc.

The second part of the reasons that cause blue screens in computers on Windows 7, lies in the hardware. Record holders in popularity are such important PC components as hard drive and RAM.

Often, after the user has inserted an additional RAM strip into the PC, or because of its poor contact in the slot, the blue background with white letters will not be slow to greet the computer owner. Also, not infrequently, problems with the hard drive are the reasons for a critical error and an OS freeze.

The blue screen itself in Windows 7 is for informational purposes only. Its text contains recommendations for troubleshooting and notifies the user of the specific error codes that caused it.

That is why it is required to carefully study all the inscriptions displayed by the death screen. By rewriting or memorizing the error codes from the bottom of the screen, you can surgically accurately diagnose and quickly get rid of the problem.

Unfortunately, often the user does not have time to get acquainted with the output of the report, so this guide begins by accepting the cancellation of the automatic restart of the PC after an error occurs.

Computer settings

If the user did not have time to capture the necessary information from the screen, then a small PC setup is required.

After that, it will be possible, having learned the code, to find an effective "medicine" that can cure an iron friend.

You need to do the following:

It is recommended to study the meaning of the error code on the bsodstop.ru resource. For example, "0x0000004e" may appear due to an incorrectly installed driver.

To find out exactly what software is causing the problem in the system, you should use the BlueScreenView application, which automatically identifies the files that cause a fatal error. The user only needs to install and open the application.

By the detected file, you can find out for which hardware you need to reinstall the drivers. From the above figure, we can conclude about the difficulties with the graphics accelerator, since "ati2dvag.dll" is associated with the video card.

In this case, installing the correct software for the video accelerator will get rid of the screen of death.

After reinstalling the driver, you need to restart the PC. If it was not possible to fix the problem, then it means that there are still other reasons.

Often an error occurs after updating or installing a new program, while the best way out of the situation is to roll back the OS.

Rollback

A new program or game is also a frequent culprit in system failures. In order to return the OS to a working state, it is necessary to perform the following sequential steps:

Installing OS updates

Microsoft is committed to troubleshooting BSoD issues.

They continue to support the outdated "Seven" and release upgrades that include "fixes" that fix system errors that cause a blue screen.

To update you need to do the following:

The next most popular cause of problems is a banal lack of memory in the system partition of the hard drive. It won't take much time to check this version.

Out of memory

On the official resource of the Windows 7 developer it is written that its operation requires at least 100 Mb of free space on the system volume, however, practical experience has proven that for the normal operation of the "Seven" it is required to keep a fifth of the system volume free.

To make sure that there is enough space in the section, you just need to open "Computer" in Explorer.

After making sure that there is enough space for the functioning of the OS, you should proceed to the analysis of the presence of system errors through the event log.

Event log analysis

To do this, you need to take the following steps:

Antivirus and viruses

Often, simply disabling antivirus software will lead to troubleshooting. If after deactivating the protective application the blue screen stops appearing, then you will need to completely remove the antivirus.

Malicious utilities also cause critical errors, and you need to regularly scan your PC for their presence. Many antivirus developers have versions of programs that run from removable media.

For example, "AVZ". By writing the application to a CD or USB flash drive, you can treat your PC from malicious utilities.

BIOS

Incorrectly entered parameters in the BIOS also often cause a failure. You can fix the situation by resetting the BIOS settings to the initial state - "default".

Equipment

The simplest revision of the worn-out loops and the correctness of their connection sometimes allows you to quickly identify the cause of the failure.

If the user has relevant experience, it is required to open the system unit (SB) and check the connections of all computer components.

For example, when, based on the results of a careful examination of the information displayed on the very blue screen, it is found that there is no access to RAM, you will need to do the following:

1. Turn off the PC;
2. De-energize the computer by disconnecting it from the power source;
3. Remove the SB cover and disconnect the RAM boards;
4. Wipe the contacts with a dry cloth and insert the equipment into place;
5. Start the PC;
6. Make sure the problem is fixed.

Similar activities can be done with the rest of the PC components, for example, with a hard drive and sound - video cards. If there is no positive result, then the failure of this component is possible and replacement with a new one is required.

Hardware diagnostics can be performed using special utilities. For example, "Windows Memory Diagnostic" allows you to identify problems with RAM.

The application writes an image of the boot disk. This ISO must be cut to a CD and booted to the PC. The program will carry out testing in a cyclic mode.

To stop the analysis, you need to reboot. Also in Windows 7 there is a built-in program for analyzing RAM. In order to apply it, you need to perform the following steps:

To minimize the risk of BSOD occurrence, the following is recommended:

Most often, the main symptom of any serious malfunction in Windows 7 is a blue screen. Moreover, its presence can indicate both problems with the hardware of the personal computer, and with the software.

In most cases, fixing problems of this type is quite simple, almost always you can do it yourself. Only occasionally may a specialist consultation be required.

Configuring the system to diagnose the problem

When Blue Screenof Death appears frequently, the first step is to perform two operations in strict sequence:

• disable reboot;
• run a special system utility.

Disabling reboot will get rid of automatic restart when BlueScreenofDeath appears. This is necessary in order to find out the error code that caused the emergency on the personal computer.

This operation is performed as follows:

After performing all the above operations, the system will stop rebooting on its own. And the user will be able to view all the information about the problem that led to the appearance of the corresponding message on the display.

Most often, the trouble lies in the PC's RAM. It is imperative to analyze it using a special utility. The OS already has the necessary software built in to achieve this goal.

It is launched as follows:

It is necessary to choose the first option, as it is optimal. It is important to remember that this type of check takes a long time.

In no case should you interrupt the process.

After its completion, the machine will restart in automatic mode. All information with the test results will be displayed on the PC display. This will help determine the remedy for the problem.

Reasons for the appearance

A variety of issues can arise from this type of problem.

But all of them can be roughly divided into main categories:

• equipment malfunction;
• inappropriate or incorrectly working drivers;
• software.

The surest way to determine a malfunction is to analyze the information present on the monitor at the moment the Blue Screenof Death appears. In most cases, the computer uses special character sets to point the user to the problem node. It is best to find the decoding of error codes on the Internet in advance.

Installed hardware failure

Very often, this type of problem appears due to a problem with the hardware of the PC. They can arise due to improper assembly, or breakdown of microcircuits. Quite often both the first and the second are present.

The most common problem is swollen capacitors on the motherboard. Finding this is very simple: you need to open the PC case and carefully examine the small bars with round legs on the Motherboard. If the end part of any capacitor is swollen, then it must be replaced. This process is quite simple, you just need to select a component with a similar capacity.

Often a similar problem occurs with power supplies. The presence of swollen capacitors in them can also lead to a blue screen. It is advisable to carefully inspect all PC components - the presence of damage (carbon deposits or other defects) indicates hardware malfunctions. Often the problems lie in the connection buses.

Drivers

Very often, Blue Screen of Death occurs due to incorrectly selected drivers. Most often this is due to the catalysts for the video card. This is especially true for applications downloaded from unofficial resources.

To solve such a problem is simple, you just need to replace the installed programs with standard ones. But sometimes it happens that dealing with a problem of the type in question is not so easy.

If the user does not have sufficient knowledge and experience in order to detect the problematic driver, due to which the BSOD occurs, then a special built-in utility should be used. It's called Verifier.exe and it's very easy to find and run it.

Software

Often BSOD occurs due to the presence of a malicious application. Antivirus will help to resolve this situation.

For now, the following are the best things to use to check your PC:

• Kaspersky Anti-Virus;
• Nod 32;
• DR. WEB;
• Avast.

Sometimes BSOD appears due to a variety of applications that, for some reason, conflict with drivers or other programs, utilities. Therefore, getting rid of the blue screen of death sometimes allows a simple uninstallation of recently installed programs.

Analysis of a memory dump with the BlueScreenView utility

If Windows 7 Blue Screen occurs - what to do? The situation can be resolved using the universal BlueScreenView application. This utility does not require installation and immediately after starting in automatic mode it detects all dump files.

With BlueScreenView, you can easily analyze a computer message.

The dump viewing process is straightforward:

• dump files are displayed in the upper part of the window - you need to click on the required one, and the drivers that caused the BSOD will be displayed in the lower area;
• you need to double-click on the desired item - this will allow you to see the parameters in a tabular format;
• click on "settings" - "selected window mode" - "drivers found in the crash track";
• right click and select HTMLReport.

The information received can be sent to the support service, or analyzed independently - if the user has the appropriate knowledge and skills for this. If necessary, you can view the original BSOD screen using the utility in question. It has a very wide functionality and many settings, therefore it is quite popular.

Common mistakes

It is quite easy to figure out how to find out the cause of the BSOD. It is much more difficult to eliminate it. Usually, the error is displayed on the monitor screen in the form of a hexadecimal code, which can be easily translated into ordinary English.

Most often, the following errors occur:

It is necessary to find in advance the translation of the error codes into English or immediately into Russian. This will make it possible to simplify as much as possible the problem of eliminating a malfunction of the type under consideration. If for some reason it was not possible to deal with the problem, then it is worth contacting competent specialists.

Avoid occurrenceBSOD or you can eliminate it after its appearance with the help of some actions:

Also, often the cause of the appearance of the blue screen of death is the installed unlicensed operating system. Perhaps installing the original distribution will get you out of trouble.

The best way to solve BSOD problem on PC is to simply prevent it from appearing. It is necessary to update the software in a timely manner, and also not to use pirated programs, operating systems. It is imperative to monitor the hardware (temperature, dustiness). All this will avoid the need to waste time fixing problems.

The question of how to be and what to do if the computer crashes into a blue screen BSOD(Blue Screen of Death, which translates as "blue screen of death") is often asked by users of computer devices, since such a phenomenon as BSOD is quite common. Symptoms of a blue screen are very eloquent, more precisely, they are “bluish”: the computer turns on and starts to boot, after which the Windows splash screen appears, and after a while the PC, without fully booting up, displays a blue screen with white inscriptions.

BSOD: reason and benefit

Many users are unhappy with Bill Gates' brainchild - Windows. I wrote, they say, a curve operating system, which now produces blue screens of different configurations. But this attitude is wrong and unfair. Many do not know that if it were not for the BSOD, if the OS crashed, many computers could be damaged and a lot of data lost.

The fact is that the Windows OS functions directly with the hardware of the computer, and if something suddenly goes wrong, the hardware of the computer device will receive an incorrect command, which can be anything (for example, delete all data from the disk). Of course, the consequences of such a command are obvious: data loss and PC breakdown.

But this does not happen, since BSOD comes to the rescue - a special defensive reaction of the Windows operating system that occurs when the OS is no longer able to account for its actions and control them, and therefore is forced to take decisive action aimed at its own emergency stop. Say, so as not to break the wood in the computer.

Thus, BSOD error, or STOP error, appears in cases such as:

• error in the Windows OS,
• hardware conflict,
• driver incompatibility,
• damage to the driver with which the OS controls the computer,
• damage to system files,
• physical damage to some components.

It often happens that a STOP error occurs when:

• launching pirated or inadequate software,
• when viruses get in,
• in case of launching third-party incorrect drivers,
• use of false antivirus programs and other "left" products.

If a blue screen occurs, you should address the causes of BSOD and the consequences of operating system errors. Fighting a blue screen is not so difficult, and even an ordinary user can get rid of bsod in computer on their own.

STOP error identification

Sometimes error identification STOPnot possible. The message about the blue screen of death looks, as a rule, not entirely clear, since it is impossible to make out what is written in the mysterious STOP error, since the computer is constantly restarted and does not allow reading the already illegible "non-Russian" text.

To understand what your operating system has written to you, and to start taking some action to solve the problem, you need to press the F8 key on the keyboard and hold it down the next time the PC restarts. After that, the menu for entering safe mode will appear. Find the item "Disable automatic restart on system failure" in the menu, and then enter the menu. Now when you start your the computer gives a blue screen with white entries and will remain in this position until you press the Reset key.

In order to get rid of the blue screen of death, do the following. Start by trying to boot your computer from a Live-CD of some kind. This will help determine what type of problem you have - hardware or software: if it is hardware, it will not work to boot from the Live-CD, and the PC will persistently issue BSODs.

Then proceed as follows:

1) Restart your computer, or better turn it off and then turn it back on after a while.

2) Remember what you inserted into the computer on the eve of the problem. Or, perhaps, you changed some "piece of hardware" - maybe it did not make friends with Windows? Perhaps you have installed some kind of incorrect program? Try to return everything "as it was" and see what happens.

3) If the OS boots, and the STOP error appears only occasionally, update the OS by taking the update from the official Microsoft website.

4) Check if the computer has enough voltage. Because if it is insufficient, the computer may issue BSOD.

5) Check your RAM. This can be done using the Memtest utility (it is on the Live-CD) or using the RAM checker that is available on the OS installation disk.

6) Check the hard disk for sufficient free space and then for bad zones using the MHDD utility (found on the Live-CD).

7) Go to BIOS, find the Default option and enable it. Save changes and restart your computer.

8) It will not be superfluous to run the "System Restore" option or activate the "Load Last Known Good Configuration" option (you can call the options via F8).

One of the following should help you eliminate blue screen on computer... If this does not happen, check your computer for viruses - they are often the cause of problems. Good luck!
